What is RFID and how does it work?

Radio Frequency Identification (RFID) is a short-distance electro-magnetic method for transmitting small bits of data. It was initially used primarily for inventory tracking, but morphed into all sorts of uses, including authentication, passports, identification cards and credit cards. It’s the latter use that has driven a billion-dollar defense industry offering specially designed RFID-blocking accessories.

You can use a myriad of materials that are poor conducts of electromagnetism to block RFID waves — just a few sheets of thick aluminum foil will do the trick .

 

RFID blocking wallets, and other products offer protection against RFID skimming. There are several products you can buy which help stop your cards being skimmed. There are RFID blocking wallets, purses, sleeves, and cards. Wallets, purses and sleeves work by acting as a Faraday cage which creates a screen around your cards which stops electromagnetic fields interacting with the cards. The RFID blocking cards are the same shape and size as a regular credit card and is placed together with the cards it should protect. It contains a jamming device that is activated automatically when someone tries to scan the payment cards in its proximity.You can buy RFID-blocking card holder,wallet and purse and here are some Boshiho  RFID blocking wallet and card holder i want to recommend you.
